JQH pneumatic winch is a kind of single drum winch powered by piston pneumatic motor. The winch is mainly used for oil field drilling (including ocean), metal mining, coal mining, construction engineering and other departments towing, or lifting heavy objects.

Because it has the characteristics of small size, light weight, adjustable speed, easy handling and quick installation, it is more suitable for underground operations in excavating mines. Such as in digging Wells, mining working face loading station scheduling, hauling harvesters and in the underground narrow roadway lifting, traction tools, instruments and other heavy objects.

Hydraulic motor basic concept: is the application of oil to transfer pressure of mechanical equipment. Oil transmission pressure in a closed container is to follow the PASCAL principle of four-column hydraulic press hydraulic transmission system system by driving mechanism, control mechanism, electric actuator, auxiliary mechanism and work on the chemical composition. The driving mechanism generally uses the oil pump as the driving mechanism, which is generally a positive displacement oil pump. In order to better take into account the requirements of the fitness speed of the electric actuator, choose one oil pump or many oil pumps. Wheel pump for bottom pressure; High pressure variable piston pump high pressure gear pump. When the inertia moment of the controlled device is large, if it is required to ensure the braking system or reverse or smooth running in a short time, the brake valve cache file should be set up in the back brake tube to prevent the damage to safety production accidents caused by large hydraulic press damage.
